For me, I would rather read a good book, from a contented author. I don’t really care what it takes to produce that.
Some writers need a while to charge their batteries, and then write their books very rapidly. Some writers write a page or so every day, rain or shine. Some writers run out of steam, and need to do whatever it is they happen to do until they’re ready to write again. Sometimes writers haven’t quite got the next book in a series ready in their heads, but they have something else all ready instead, so they write the thing that’s ready to go, prompting cries of outrage from people who want to know why the author could possibly write Book X while the fans were waiting for Book Y.
I remember hearing an upset comics editor telling a roomful of other editors about a comics artist who had taken a few weeks off to paint his house. The editor pointed out, repeatedly, that for the money the artist would have been paid for those weeks’ work he could easily have afforded to hire someone to paint his house, and made money too. And I thought, but did not say, “But what if he wanted to paint his house?”
